COATING APPARATUS.

Application filed December 21, 1918.

T 0 all whom it muy concern:

Be it known that l. lux C. lircltnixsrnn, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain lmY provements in (loating Apparatus, of which the following description. in connection with the accompanying drawings. is a specification, like reference characters on the drawings indicating like partsl in the several figures.

lily invention relates to apparatus t'or applying a coating fluid. as cement, to various objects. ot' which shoes furnish an example. In such work, especially in connection with tennis shoes. it may be desired to coat the lower edge of the upper to attach the foxing. or to thus treat the bottom of the innersole and the adjacent portion of the toxing for laying the outersole. ln the firstmentioned operation especially, it is important that the upper edge ot the coated surface be uniform and symmetrically located with relation to the bottom ot' the shoe. It is the purpose of the present invention to 'furnish means Jfor obtaining this result.

A feature of the invention consists in a receptacle for a coating Huid and Ineans movable relatively thereto to remove fluid above a predetermined level, and with such an organization the Work, it dipped a definite distance into the fluid. will be coated to a uniform height. Preferably the level-determining means operates intermittently. as between successive dipping operations, and may consist of a bar or other member movable across the top of the receptacle. This serves to level the Huid. which it it be cement or other viscous substance may rise considerably above the top of the receptacle, to the desired determined depth therein.

The distance to which the work is dipped into the coating fluid is limited by a support in the receptacle, and. to alter the relation of the upper line of the coating to the work, as a further feature of the invention I prefer to adjust diferent portions of the support independently, thereby rendering possible a change in the angular relation of the upper line of the coatlng to the Work.

, This is of especial utility in adapting the apparatus for ooating different types of shoes. v Y

Another feature of the lnvention has to Specification of Letters Patent.

Serial No. 267,805.

do with conveying means, receiving coating fluid from a suitable source and delivering it to the applying receptacle. this conveying n haus having a plurality of outlets provided with controlling means. one. in the present instance` being opened while the other is closed. This arrangement permits the conveying means to operate continucmsly. The control ot the outlets is herein shown as eti'ccted by power mechanism and preferably through the action oi' the depth-dctermlning means. llpon actuation oi' the outlet closures the controlling means may be locked temporarily to allow a flow oi' tiuid through the outlet leading to the receptacle to till this. The {luid-conveying means is further controlled incidentally to an act pert'omed upon the work. This control. in the present instance. consists in the release of the lock for the outlet closures by contatt with the work as it is presented to a cleaning member.

Other features ot' the invention will hereinafter appear. reference being had to the accompanying drawings. in which Fig. 1 is a top plan view ot' a particular embodiment otl the invention.

Fig. L) is a side elevation thereof, looking from the bottom of Fig. 1. parts being broken away;

Fig. il is a vertical transverse section on the line 3h25 of Fig. 1; and

Figs. l and 5 are central vertical sections through the applying receptacle, these illustrating the application of the coating Huid to the heel and ball portions and to the toe portion of a shoe. respectively.

At 10 appears a tank or container serving as a source ot supply for cement or other coating Huid. At one end ot this tank is a well 1Q, the contents of which may be withdrawn for cleaning through an opening normally closed by a plug 14. At one side of the well the tank has a laterally projecting portion 16 provided with a bottom Wall 18 inclined from the outer end of this lateral portion toward the well to permit cement falling `upon the incline to return to the well. Supported near the top of the tank portion 1G by lugs 20 is a pan or applying receptacle 22,u the upper edges 24 of which lie in a common horizontal plane. Receiving Huid from the well is a conveyor consisting of a vertical screw 26 rotatable in a cylindrical casing 28. The lower end of this casing extends into proximity with the bottom of the Well beneath the cement therein, While the upper end terminates in a head 30 having spouts 32 and 34, the first delivering to the pan 22 and the second to the Well. At the top of the screw is a spindle projecting through the casing head, upon which spindle is secured a pulley 36 to which power may be applied to actuate the conveyor by a belt 38 passing over guide pulleys 40 and about a pulley or belt surface 42 rotatable upon a shaft 44 journaled near the bottom of the apparatus. The pulley 42 is integral with or carried by a pulley 46 belted to a suitable source of power. this last-mentioned pulley being joined to the shaft 44 When desired by a single-revolution clutch of any convenient type controlled by a lever 48.

To support the Work in predetermined relation to the edges 24, there is located within the applying pan a table 50 to the under side of which standards are pivoted at 54. These standards pass through and closely fit openings 50 in bosses near the opposite ends of the bottom of the pan and are threaded through spiral gears 56 held against. downward movement by brackets 58 carried by the pan. lith these gea-rs 56 mesh like gears 60 upon shafts 62 journaled beneath the pan. applying a Wrench to the squared ends 64 of the shafts 62 the standards 52` and therefore the corresponding ends of the table, may be independently raised or lowered and the distancev between the table and the top of the receptacle altered.

To determine t-he Huid level in the pan 22 by removing any excess which may rise above the edges 24, a member 66 is provided, this being shown in the form of a bar extending transversely of the pan and mounted to slide on the opposite side edges. The bar has cylindrical end portions 68, 68, each entering a slot 70 in the. upper extremity of a lcver'72 fulcrumed at 74 near the bottom of a casing 76 integral with or attached to the tank. To draw the bar 66 into contact with the top of the pan, tension springs 78, 78 extend from the ends 68 of the bar along the levers 72 and are connected to the latter by a rod 80 which passes through openings in the levers. To the center of this rod 80 is articulated a connecting rod 82 'oined to a crank 84 upon the shaft 44.

Vlien the pulley 46 is clutched to the shaft 44, as a result of the operation of the lever 48, the crank oscillates the levers 72 so that the bar 66 travels from the end of the pan adjacent to the conveyor to the opposite extremity` striking off any cement which rises above the edges 24. The forward edge of the bar is preferably provided with oppositely inclined faces 85,85 diverging from its center, which tend to throw the Huid to the sides of the pan rather than to force it before the bar.

The outlet openings of the spouts 32, 34 are controlled respectivel by Valves 86 and 88 which may be pivote upon brackets 90 projecting from the head 30. Normally, the valve 86 is open and the valve 88 is closed, the conveyor thus delivering the coating fluid from the Well to the pan. To change these valves so that the supply is cut off from the pan and the flow diverted back to the well, their position is controlled by the level-determining bar. For this purpose the valves 86 and 88 are respectively joined by links 92 and 94 to a bell-crank lever 96 fulcrumed on a bracket 98 carried by the spout 32. From the lever 96 a rod 100 extends into proximity with the opposite extremity of the tank, Where it slides through a guide. 102. Near the guide the bar 100 has a downward projection 104 with which the bar 66 contacts near the end of its leveling movement. This shifts the rod 100 to the left as viewed in F ig. 2. swinging the lever 06 about its fulcrurn to close the valve 86 and open the valve 88. The parts are temporarily locked in this relation against the tension of a spring 106, by a latch 108 fixed upon a shaft 110 journaled across the top of the tank and engaging a depression 112 at the upper side of the rod 100.

The valves are further controlled to allow the spring 106 to return them, by contact of the work incidentally to an act performed upon it by the operator. At the end of the tank opposite the Well is journaled a hori- Zontal ro-ll 114, the periphery of which is in proximity to the end of the applying pan. This roll is constantly rotated by a pulley 116. over which a belt 118 passes to al pulley or belt surface 120 rotatable With the driving pulley 46. Near the center of the roll 114 is a circumferential depression or groove 122, and in this groove With its side projecting beyond the periphery of the roll is a contact finger 124 secured on the shaft 110.

The finger is yieldably held with its edge outside the groove and the latch 108 pressed against the top of `the rod 100 to enter the depression 112, by a spiral spring 126 surrounding the shaft and connected to it and the shaft bearing. The surface of the roll is utilized in its rotation to remove any excess of cement which there may be upon the work after it has been dipped in the pan, by presenting the surface to be cleaned to the roll, and, when this is done, the nger 124 is forced down into the roll-groove, lifting the latch from the depression in the rod 100 and permitting the spring 106 to restore the outlet valves to their normal position. To clear the roll of accumulated coating Huid, there is mounted upon a yoke 128, extending across the top of the tank beneath the roll, a scraper having sections 130, 13d contacting with the cleaning surface and a narrow central section entering the groove 122.

Assuming that the apparatus is to be employed for cementing shoes for vfoxiugs or outersoles. the Well portion l2 of the tank is supplied with cement. and, power being applied to the apparatus through the pulley 4G. the conveyor screw 2G continuously raises cement from the Well and in the normal posiM tion of the outlet val `ses delivers it to the pan. For cach shoe to be cemented the operator actuates the lever a8, tripping the clutch controlled thereby, which causes the bar 6G to travel the full length of the pan 22, striking ofl' the cement rising above the edges 24. lhen the bar reaches the opposite end of the pan trom the conveyor. it contacts with the projection of the rod 100, shifting this` and therefore the valves, to shut off the supply ot' cement from the pan b v the closure of the valve 8G and turn it back to the well through the opening of the valve 88. The operator now places the shoeon the table 50. as illustrated in Fig. l of the drawings, with the heel and ball portion of the shoe bottoni resting upon it. This causes the rement to rise u on the shoe to a line determined by the ai justment of the table relatively to the edges 2l of the pan. The table height may be varied, not only to change the po sition of the upper line of the cemented surface but also its angle longitudinally of' the shoe. Then moving the shoe to the left,

as seen in Fig. 5, the operator rocks it upon 1 the ball portion to lower the toe into the cement, thus completing the coating to a uni- `form exent along the entire edge of the upper. As the movement to the left continues, the bottom of the shoe is broughtl into contact with the roll 114 and any excess of cement thereon is wiped oil". At the same time, by contact ot' the work lwith the finger 124, the latch 108 is raised and the rod 10() released, restoring the outlet valves to their initial position. This results in the pan being refilled for another operation.
